As a distinguished figure in the realm of clean beauty and skincare, I can provide some insights on the topic. Snail mucin is a popular ingredient in skincare products due to its potential benefits for the skin, such as hydration, soothing, and improving the skin's texture. However, when it comes to using snail mucin during pregnancy, it is essential to exercise caution.

While there is limited research specifically on the safety of using snail mucin during pregnancy, it is generally recommended to avoid ingredients that have not been extensively studied or proven safe for use during pregnancy. Snail mucin contains various compounds, including glycoproteins, hyaluronic acid, and peptides, which may have the potential to interact with the hormonal changes that occur during pregnancy.

To err on the side of caution, it is advisable to consult with a healthcare professional, such as a dermatologist or obstetrician, before incorporating products containing snail mucin into your skincare routine during pregnancy. They can provide personalized advice based on your specific circumstances and help you make an informed decision about which skincare ingredients are safe for you and your baby.
